“[Shani] just went flying [in the crash] — her face doesn’t even look like her at the moment,” Ms Bourne’s sister, Kiandra Bourne, said.

“Everyone’s ... missing her terribly, her two boys especially and feeling helpless but we are all just so, so thankful she is alive.”

Mr William suffered a broken arm in the accident.

Fairfax reported the couple were due to fly home to Canberra on Tuesday, December 5 but became stranded in Thailand, with insurance unable to help cover the $80,000 needed for medical transport home.

On the weekend, Ms Bourne’s orthopedic surgeon said her fractured pelvis was well enough to fly on a commercial airline, however doctors said the swelling in her nose would have to go down before she took a flight.

A new message on the campaign page reveals Mr William’s workers union has agreed to help out with some medical bills.

“This was amazing news and a great relief, the funds we have now raised will be enough to get Shani and Sam home, cover incurred costs, assist with rehabilitation, and any further medical expenses that may occur when they get home,” the page reads.

“If there is any money left after these expenses the donations from gofundme Shani and Sam will be donating to a worthy cause, or to assist other people in need or in similar situations.”

Kiandra Bourne said the pair’s insurance claim was knocked back as Mr William’s Australian motorcycle licence had lapsed.

The accident is the latest in a spate of incidents involving Australian travellers this year.
